Science is a vital part of our lives. From understanding why the seasons change to predicting where meteors come from, science plays a key role in everyday life.

Unfortunately, many students struggle to grasp the basics of science. It can be quite complicated wrapping your head around all these new concepts.

It’s Not Rocket Science - 15 Engaging Science Worksheets For Third Graders

However, science is supposed to be fun! If you teach it in the right way science can be extremely fun for kids and they become ever so engaged with it. 

The third-grade curriculum provides an excellent foundation for learning about the world around us.

It is the perfect time for children to further develop their understanding of basic scientific concepts. 

If you are looking to help teach the 3rd graders in your life to learn more about science and help them see how fun it can be, you’ve come to the right place.

We’ve put together a list of 15 engaging worksheets for those in third grade to complete. 

Is The Moon Out Tonight?

Learning about the moon is one of the most important things that we do as humans. Without the moon, there would be no night sky.

That is why it is vital that your children learn about why the moon is important and the phases of the moon. 

This fun activity gives the third-graders a chance to learn some background knowledge about the moon.

Then they have the chance to apply the knowledge they have learned with the knowledge of the moon they already know. 

It is a good way to see the third-graders’ understanding of how the moon appears in the night sky.  There are even some more challenging questions as the children work through the sheet.

We love that this worksheet still allows the children to be creative by asking them to draw the moon.

Bones Provide Great Support

Bones are very important to our bodies. They provide support and protection for our muscles and joints. When bones break or wear down, it can cause pain and discomfort.

This is why it is important that your child learns about bones. 

In this activity, the third-graders learn about our skeleton. They are provided with some background information on our bodies. They are then asked to draw arrows to the correct body part.

This activity is a great way to build their understanding of the skeleton, as they are given new information, and then they have to apply this information.

The science investigation task on this worksheet asks them to draw their hands and the bones in them. 

Catch A Ray Of Sunlight

Learning about light is something that might be new to a lot of third-graders.

It’s something that they will experience every day. So, it’s important that they understand what light is. 

In this activity, the third-grade students are given a picture in which they have to draw the rays of sunlight and how they reflect.

This might be a new concept to some third-graders, which is why it is great this worksheet has some information for the children to absorb before they do the task. 

We like the fact that the science investigation allows the children to be more curious and aware of their surroundings.

This investigation asks them to observe the changes that occur when they put different objects between two mirrors. 

What Are Germs? 

Third-graders might not know much about germs. But, they may be familiar with the idea that some things can make them ill. So this is a great worksheet to expand on their knowledge. 

In this worksheet, the children are introduced to the topic of germs. They are asked to write about what germs are, if all bacteria are harmful, and explain all they know about viruses.

The worksheet provides them with all the information they need to know in order to answer this question. 

There is also a multiple choice quiz on this worksheet, which is a great way to test their understanding of what they have just read. 

Attract Or Repel?

Magnets are something children often find themselves playing with. And there is no doubt that they enjoy using magnets. 

The magnetism of magnets is one thing that many third-grade children don’t yet fully understand.

In this worksheet, the third-graders are introduced to the basic concepts of magnetic attraction and repulsion.

They are asked to complete the images on the sheet and label whether they attract or repel each other. 

This worksheet gives children the chance to play with real magnets through the science investigation part.

It provides them with the opportunity to conduct their own experiments with magnets and write down their observations.

We like this part of the worksheet because it allows the third-graders to apply the information they have learned to the real world. 

Life Cycle Of A Plant

Third-graders are often learning about plants at school. They are learning about the life cycle of plants.

This means that they are being taught about how plants grow from seed to flower, produce fruit, and eventually die. 

This worksheet is a great way to test the knowledge of your third-graders.

There is no other information that comes with this worksheet as it should be used to assist in the lessons that are being taught about the life cycle of a plant. 

There are pictures on this worksheet that can help to guide the children who are still not confident about the life cycle of a plant.

However, the primary focus of this worksheet is to be able to identify if the third-graders are able to put the life cycle of a plant in their own words. 

Day And Night

Children love to learn about the sun. They will often ask questions about the sun such as: How does the sunshine?

What happens during the day and night? Why do we sleep? These are all questions that children often ask us. 

This worksheet introduces the concept of day and night. It explains the difference between day and night and why it takes 24 hours for the earth to rotate around its axis once.

Children are then given an opportunity to draw an arrow to show which side the sun is shining on. 

As part of a science investigation, this worksheet asks the children to spin a glob and put a light on it. This helps the children to get a better understanding of what they are being taught. 

Properties Of Objects

Learning about the properties of objects is something children have been doing their whole lives, they just don’t realize it.

This worksheet teaches the children about the properties of objects by asking them to pick the best word to describe the object. 

Since there are multiple objects on the worksheet, the third-graders will often start to compare the objects.

This helps the children to gain a better understanding of the properties of different objects. This worksheet is a great way to introduce the basic concepts of objects to the students. 

A Whale Of A Story

A Whale Of A Story

Learning about different animals is a sure way to get the third-graders engaged in their science lesson. Whales are often animals that mystify children.

They are forever in awe of how big they are and when children are young, they can’t seem to grasp the size of a whale. 

This specific worksheet focuses much more on the sound a whale makes and how far it can travel.

The children are provided with background information to help them develop a small understanding of how sound travels. 

We like that this worksheet is about sound and how fast sound travels, but with the use of the whale story, it feels like the children are learning about whales. 

Reduce, Reuse, And Recycle

An important lesson that all children learn at some point is to recycle.

This worksheet encourages the children to think about how they can reduce waste and reuse things instead of throwing them away. 

The worksheet provides the children with all the information they need to know in order to complete it.

It describes what the three terms mean and gives them examples so they are able to have a clearer understanding. 

This worksheet is a great way to test the knowledge of all the children.

There is a multiple-choice quiz where the children must answer questions based on the information they have learned from the worksheet.

They also have a writing task to do, which ensures that they are able to put what they have learned into their own words. 

All-Weather Gift Wrap

Learning about the properties of different materials is a key component of any science lesson.

In this worksheet, the children are asked to look at different types of materials and determine whether they would be suitable for wrapping gifts. 

Third-graders may have a slight understanding of what waterproof means, especially if they have their own raincoats.

This worksheet expands on that knowledge. It helps children learn which materials would be waterproof and which would be absorbent. 

This worksheet has a diagram that shows the reaction of the different materials to water. They have to use their knowledge to work out if this would be a good material to wrap a gift in. 

As part of their own investigation, this worksheet asks the children to come up with their own experiment.

This hands-on approach, helps them to understand the concept of waterproof materials. 

What Living Things Need To Survive 

Third-graders love to learn about living things. This worksheet is perfect for getting them started. It introduces the idea of survival and explains what living things need to survive. 

This worksheet has a lot of information and writing on it, so it might be best if you went through this information with the children.

However, since the worksheet has all the information on it, the children can refer back to it when doing the tasks. 

There is a writing task and a quiz on this worksheet. This is so the children are able to put into their own words what they have learned. 

Animal Homes

Teaching about animals is always a hit with children. They are often very engaged in learning about how some of their favorite animals live their lives.

This worksheet is designed to teach third-grade students about animal homes. 

This worksheet helps third-graders gain a basic understanding of different animal habitats.

The worksheet has a task where the third-graders need to sort different animals into the habitat they think they are meant to live in. 

The worksheet then allows the children to develop their understanding of habitats by having them select one and make a poster about it. 

Eating A Balanced Diet

One of the most important lessons for third grade is nutrition. It helps children understand why they need to eat their vegetables.

This worksheet teaches the children about eating a balanced diet. 

This worksheet includes a number of activities that help the children to understand the importance of eating healthy foods.

These include a written task explaining what happens if people do not have a balanced diet and a quiz. 

Human Body Parts

Learning about the body is an important part of third-graders understanding more about themselves.

This worksheet is a great way for teachers to test the understanding their students have about the body. 

This worksheet does not come with any information which is why it is a good worksheet to use in a lesson, based on the information teachers have explained.
